Oh I know just what you mean. I had to put the pot back and the zeners for the bias adjustment that was so fun lol. You made me wonder because my 6 tuber have another variable cap on top by the pi circuit. I was curious. No matter what I've done it won't go below 1.7 I am not to awful concerned...

Yes sir, with the amp off my pass though is 1.2:1 with it on 1.7 is the lowest I can get it to go. I am going to have to remember that I never knew that they could he driven that hard. Thank you for the info I will have to look around for more variables.

Oh yea I know just what your talking about. I found a sweet spot the lowest I could obtain was 1.7:1 which I mean isn't to awful my output swr is 1.3:1. 73s I appreciate your reply.

How did you get your input swr down? I have played with this thing for a while. I can't get it below 2:1. 500 PEP damn that's pretty sweet. I'm getting about with 1.5 wdk in I'm getting 20 swinging to 350. 73s man

My apologies on the late reply you are correct it is a .002 1KV ceramic cap. It's a decoupling cap for the ac line the yellow wire goes to the fuse holder and the other end to ground.

Now that it's gotten dark our I shut all the lights off and tested it one more time before I fully buttoned her up and its still very slightly turning red. Going to replace all the cathode resistors and parasitics in time and see if that helps. Still stumped it's only the one tube. I was...

Wow I feel like a dunce. I checked that socket out. So pin 2 and 6 are the grids obviously, some of the sockets has pin 6 removed others are left intact.. The one in question has both pin 2 and 6. So I removed everything off the pins completely isolated it and I found pin 2 intact but when I...

Yes, it's only one of the 24lq6 driver tubes. I was thinking about adding bias to the driver tubes like the 6 finals but I'm only seeing failure on one tube if it was all of them cherrying I understand that but just one I don't understand. I sprayed the sockets and checked continuity, but you...

Hello all, I have a 10 tube 24lq6 with a 6kv6a pre driver tube. The number 2 driver tube 24lq6 is red plating with just a few seconds dead key or talking. I've changed out the z14 plate choke, the 47ohm parasitic suppressor, 100 ohm cathode resistor, .01uf filment decoupling cap . Also tried...

Old post but in case anyone else finds this. I ran across one with a part manufacture defect. The SSB switch was backwards. I learned this inadvertently after recapping one and upon turning it on I noted on SSB the relay was going nuts and on AM the receive kept dropping out. SSB is shown on the...

Well after 3 years since I wrote this post I finally buttoned it up. Removed the capacitors bridged across the original ones. Added 4 new electrolytic with new bleeders. New OA2 tubes and new zener diodes for the bias chain. If it fails again, I will be be upgrading to the TIP 50 configuration...

With all this tape and crap in here I'm at a loss what the heck this last guy was thinking

Looking at that section that feeds into those filter caps it looks like the previous owner tied the transformer directly to one of the caps and the standby and operate switch are breaking the plate voltage. I see three relays on the back panel. Which one feeds the b+? This wire coming off the...

Okay. Sounds like a start. Haven't looked at the relay.

Palomar Skipper 300 I converted to 6KD6. So to preface this for better understanding i bought this amp a month ago and it was DOA. I knew the tubes where probably trashed but I was replacing them nevertheless. Came with the 8950s so I knew it was probably over driven. Two of the four rectifier...
